To all whom it mag concerm. V 7

Be it known that 1, DAVID G. GAriBRAITH, a citizen of the United States, reslding at Mineral Wells, in the county of Palo Pinto and State of Texas, have invented a new and useful lmprovementin Clamps for Holding Files, Bundles, and Such like, of which the following is .a' specification. V

My invention relates to the-improvements in paper clamps, in which a desired spring wire is formed in the shape'of an equi-angular triangle" in general outline, and the object of my improvement is, to provide open reversible set spring jaws which converge from'a common base, having inturned free ends, each end being doubled back to contact with the adj acent side of the triangle substantially midway of its length, the aws crossing a slight distance fIOHl' the doubled ends.

I attain this object by the device illustrated in the accompanying drawing, in wh1ch Figure 1 is a plan view showing the com The device has the shape of an equiangular triangle and comprises a base 1, converging bends 2+2, extended converging set spring jaws 3-8, with inrturned bends 4ci, the free ends being doubled back to contact midway of th in Fig. 1.

55 with the I. 3 9-8 substantially 8 sides f the triangle, as shown When the clamp is in open position as shown in Fig. 3, the. jaws are not in contact 1 but-are a short distance apart.

In this condition'the clamp is placed on a paperfile. Ifthe thickness'of the file, or package of papers'is less than one-third the length of the base 1, the clamp should be reversed, by turning the base through an angle f 180 degrees, thereby closing the clamp and in creasing the clamping pressure as shown-in Fig, 4. When placed on a file having a thickness from one-third to two-thirds the length of the base 1, the'clamp should not be reversed When removing the clamp from a thick file, it should not bereversed, but with a slight twist of they base it can be 3 pulled off. The ends being-turned in andv contacting with the jaws substantially inid-, way of their length do not scratch the paper when the clamp is being I claim applied or removed.

' 1. A'paper clamp formed of spring wire, and having substantially the shape of an equiangular triangle, said clamp comprising a base, converging spring jaws at the ends of thebase, the free end of each jaw being turned in and doubled back to contact with said jaw substantially midway of its length, the jaws crossing a slight distance from the doubled ends.

QJ A paper clamp as claimed in claim 1, in which the jaws at the point of crossing are a short distance apart, whereby IclamP- ing pressure may be increased'byturning the j clamp throu h an angle of1 80 degrees. DAVID G. GALBRAITH.
